Embodiment Construction
[0018] see Figure 3-4 , image 3 It is a schematic diagram of the front structure of the three-core electric heating cable for pipe penetration of the present invention. Figure 4 for image 3 The B-B section diagram. Depend on image 3 with Figure 4 It can be seen that the three-core electric heating cable for wearing pipes of the present invention consists of a core wire 1, a first insulating layer 2, a second insulating layer 3, a packing layer 4, an inner sheath 5, a shielding layer 6 and an outer sheath from the inside to the outside. Set of 7 is composed of seven layers. There are three core wires 1 .

The invention relates to a perforated tube three-core electric heating tape which is mainly used for laying perforated tubes on the surfaces of pipelines of petrochemical industry, fire control, steel, electric power and the like and is also suitable for perforated tubes of storage tanks, heat supply of civil architectures, snow melt and the like. The electric heating tape is formed by sequentially compounding three core wires (1), a first insulating layer (2), a second insulating layer (3), a padding layer (4), an inner jacket (5), a shielding layer (6) and an outer jacket (7) from inside to outside. The perforated tube three-core electric heating tape can greatly reduce the traction resistance and reduce the risk of damaging the cable insulating layers during perforating tubes.
Description
(1) Technical field [0001] The invention relates to an electric heating belt. It is mainly used for pipe laying on the surface of pipelines in petrochemical, fire protection, steel, electric power, etc. It is also suitable for floor heating and snow melting pipes for storage tanks and civil buildings. It belongs to the technical field of electrothermal devices. (2) Background technology [0002] During the construction process, the electric heating belt needs to cross highways, bridges and tunnels or buried pipelines, and the three-core electric heating belt needs to be passed through the pipe when the user's old pipeline is used for renovation. The three-core electric heating cable for pipe penetration is to provide heat compensation to the pipe or container, so as to achieve the purpose of insulating or heating the medium in the pipe or container. [0003] Structural principle of pipe-through electric heating belt: [0004] Pull the electric heating cable into the embed...
